Honda CRF450 read and write ability

[akaponch]

Does anyone here have knowledge on reading and writing to any 2017-2023 Honda CRF450 ecu? I have been trying to read with honda flasher kline and all i can do is diagnostics and sensor readings. I have tried mcuinnovations software without luck. Here are some part numbers that i have tried to read

I have tried the 2 different softwares and they won't read. I can only read with HRC software for mode 2 and 3. I would like to change the main maps. I have opened the ecu to see what chip is in it. It is kt2021kr, I saw honda flasher list that as 128kb but I still couldn't read. Any help would be appreciated.

I bought a different cable to see if maybe that is my problem. I was thinking my communication was good since I can read and write the mode 2 and 3 with HRC software. I'm just trying all I could.

I tried the new cable and that one didn't connect with HRC software nor the others to read ecu info.
I'll stick to my original KLine cable. That one reads computer info, live data, and I can program with HRC software. So I'll wait to see if anyone here knows of another software that might read and write to this ecu. 🤔

Help me out. Let me know what you guys use to read.

Thanks

This doesn't help me to read or write.. 🤔🤔

Do you want me to pay for a service🤷🏽~♂️

Or just bragging that you can.

Give me some help or address to send it or price for your help..

Maybe offset that I should start the read.

Hey there! Also interested in figuring out how to get into these ECU's. More specifically the 38770-MKE-A52 from the 450L and 38770-MKE-AK1 from the 450RL. I've heard these are tamper-proof. Is it still possible to get into them for map configuration?
